标题: molpro中SAPT能量分解求助
初次做能量分解，用DFT-SAPT方法。体系是由两个同种金属有机配合物及其反荷离子组成的二聚体。输入文件是照着molpro手册中SAPT能量分解给出的例子写的，例子见http://www.molpro.net/info/current/examples/near_sapt_acdft.com
因为例子中是两个惰性气体间的能量分解，每一个单体的原子就只有一个，而我的体系中每一个单体就有56个原子，所以我参照例子写的输入文件如下

这么大体系想做DFT-SAPT基本没戏，算不动
建议你用GAMESS-US做LMOEDA能量分解，这种规模还算能算得动
Gaussian+Multiwfn也可以做简单的能量分解，看multiwfn手册4.100.8节的例子。

谢谢sob老师，已经在研究用Gaussian+Multiwfn能量分解了。既然molpro中DFT-SAPT对于该体系没戏，那我就放弃这种方法。

请问，这里面的交换相关渐进式的矫正是必须的吗？没有实验值的话，可以用计算值吗

是。
可以用高精度计算值，比如CCSD(T)/cc-pVQZ

老师您好，想问一下对于一个中性分子一个带一个负电荷的离子（硫酸氢根）构成的二聚体计算SAPT时，电荷应该怎么写？我看手册上说WF,[NELEC=nelec],[SYM[METRY]=irrep],[spin= spin],[CHARGE=charge]，这一部分可以设置分子的电荷以及自选多重度，我自己尝试写了一下，拿不准，麻烦老师能帮我看一下吗？附件中分子B就是负离子。
